This is a prospective, longitudinal, single-center study designed to evaluate the long-term changes in symptoms and tear production in subjects with dry eye disease. The study is randomized and investigator-masked, with subjects assigned to either the TRYPTYR (Acoltremon ophthalmic solution 0.003%) arm or the control arm (Refresh Classic Preservative-free). The study will be conducted at a single site, with subjects undergoing assessments at baseline and at months 1, 3, 6, 9, and 12.

This prospective single-center study evaluates the effect of dry eye disease and short-term ocular surface treatment on the agreement and repeatability of corneal astigmatism measurements in patients with age-related cataract. Participants undergoing preoperative cataract evaluation are classified into a control group or a dry eye disease group according to ocular surface symptoms and objective tear film findings. All participants undergo ocular surface assessment and repeated corneal measurements using three commonly used devices: IOLMaster 700, Pentacam AXL, and iTrace Prime. Measurements include keratometric corneal astigmatism, total corneal astigmatism, and vector components of astigmatism. Patients with dry eye disease receive 0.3% sodium hyaluronate eye drops four times daily for 2 weeks, after which ocular surface assessment and device measurements are repeated. The primary objective is to determine whether dry eye disease reduces interdevice agreement and test-retest repeatability of corneal astigmatism measurements, and whether short-term ocular surface treatment improves measurement stability. Interdevice agreement is assessed using Bland-Altman analysis, and repeatability is evaluated using within-subject standard deviation, test-retest repeatability, and intraclass correlation coefficient.

Prospective, multicenter, randomized, vehicle-controlled, double-masked, study of CAM-101 topical ophthalmic solution compared to vehicle control followed by crossover to long-term follow-up open-label treatment with CAM-101 for one year.

Dry eye syndrome is a multifactorial pathology of the ocular surface. Epidemiological studies report a prevalence of 15% in adults aged between 50 and 95. Depending on the severity of the disease, different treatment strategies may be proposed. The use of autologous serum eye drops (AS) represents an interesting therapeutic alternative for the most severe forms of the disease, due to the serum's composition, which is similar to that of tears. The mechanism of action of AS is still controversial, but is probably multifactorial and seems to be based on growth factors, vitamin factors and anti-inflammatory factors. The clinical response of patients could be dependent on the protein composition of the eye drops. The investigators are aiming to highlight a difference in serum protein composition that could explain the differences in clinical response between patients treated with autologous serum eye drops and to identify the proteins that would be involved in a clinical response or non-response.

This is a Phase 2 clinical study designed to evaluate the safety and efficacy of 0.25% RCI001 Ophthalmic Solution compared with placebo in participants with dry eye disease. The study will enroll adults with dry eye disease. After a 2-week run-in period with placebo ophthalmic solution, eligible participants will be randomly assigned to receive either 0.25% RCI001 Ophthalmic Solution or placebo ophthalmic solution in both eyes for 4 weeks. Study treatment will be administered either twice daily or four times daily, depending on the assigned dosing regimen. The main purpose of the study is to determine whether RCI001 improves the signs and symptoms of dry eye disease compared with placebo. The primary assessments include total corneal fluorescein staining and ocular discomfort at Day 28. Safety will be assessed through eye examinations, visual acuity, intraocular pressure, drop comfort, and adverse event monitoring.

The central hypothesis is that inflammation contributes to dry eye and that rinsing the palpebral conjunctiva, bulbar conjunctiva, and fornices will reduce the inflammatory burden on the ocular surface.

Dry eye disease is a major ophthalmic health issue that severely affects the visual function and quality of life of the national population. Its core pathological mechanism involves a vicious cycle of ocular surface inflammation and neural abnormalities; however, clinical practice still lacks an objective and quantitative gold standard for diagnosis. Although in vivo confocal microscopy (IVCM) enables cellular-level, in vivo observation of the ocular surface, image analysis remains heavily dependent on manual interpretation, highlighting an urgent need for an intelligent quantitative framework.This project aims to construct a high-quality, standardized ocular surface imaging database and develop a high-precision deep learning algorithm to achieve accurate segmentation and quantification of corneal nerves (including both whorl-like and linear patterns) and inflammatory cells, and to validate their associations with clinical indicators of dry eye disease. The ultimate goal is to develop and evaluate an IVCM-based multimodal intelligent diagnostic system for dry eye, transforming IVCM from an observational tool into an intelligent decision-support system, with real-world performance validated through an independent prospective cohort.This project is expected to establish a multimodal AI diagnostic model for dry eye, create a standardized computational framework for imaging biomarkers, and enable a paradigm shift from qualitative description to quantitative diagnosis. The findings will provide reliable decision-making support for precision subtyping and personalized treatment of dry eye disease, advancing ophthalmic practice toward a data-driven, intelligent paradigm.

The purpose of this study is to examine the impact of nasal spray treatment on Meibomian gland function and ocular surface health in symptomatic dry eye patients with mild to moderate Meibomian gland dysfunction (MGD).

This is a prospective, multi-center, randomized, sham-controlled clinical investigation designed to evaluate the safety and effectiveness of the Lacrima VR system in adult subjects with Dry Eye Disease (DED) and Meibomian Gland Dysfunction (MGD). Subjects will be randomized in a 1:1 ratio to receive either active Lacrima VR treatment or a sham device with reduced luminance. Effectiveness will be assessed primarily by change in Tear Break-Up Time (TBUT), and safety will be evaluated by the incidence of device-related adverse events.

The primary objective of this study is the assessment of three tear substitute formulations in terms of postoperative discomfort following cataract extraction surgery by means of phacoemulsification and intraocular lens implantation.

This study compares ocular lipid layer thickness (LLT) measurements obtained from three commonly used clinical diagnostic devices to evaluate their agreement and consistency. It further examines which device's LLT measurements show the strongest correlation with established clinical indicators of dry eye disease severity.

patients from a Neuro Ophthalmology who have dry eye, some of which have neurotrophic keratitis are being analyzed after treatment with Vevye

The bulk of dry eye patients are found in the community. The lack of satisfactory protocols and confidence is a significant deterrent for practitioners to manage such patients, which may result in inaccurate referrals, and unhappy patients. Problems are compounded by comorbidities of dry eye, even if these are not diagnosed formally. Aligning with the healthcare strategy to move beyond healthcare to health, and beyond hospital care to community care, investigators propose that the confidence of primary carers be increased by using an image-based screening system. This study aim to determine the efficacy of this screening AI algorithm, a prototype, in addition to or instead of screening of dry eye using a simple DEQ-5 symptom questionnaire.

This is a single center, open label trial to evaluate Lifitegrast Ophthalmic Solution 5.0% in Dry Eye Disease using In Vivo Confocal Microscopy (IVCM

This study aims to find out whether adding sodium hyaluronate, a moisturizing ingredient commonly found in artificial tears, makes autologous serum eye drops more effective for treating moderate-to-severe dry eye disease. Each participant will use one version of the drops in one eye and the standard version in the other eye. The goal is to see if the new combination provides better relief, comfort, and eye surface healing compared to the traditional formulation.

This research study is to see if using Lacrifill is safe, easy to use, and helpful for people who wear contact lenses but can't wear them comfortably for long. Specifically, the study aims to determine whether regular use of Lacrifill over a 2-3 month period can help people wear their contacts longer without discomfort and reduce signs and symptoms of dry eye.

The goal of this study is to better understand how eye blinking behavior is linked to the stability of the tear film, in adults aged 18 to 65 years, with or without symptoms of dry eye. The main questions are: * Do the results of a New Blink Task reflect tear film stability ? * How are the blink related metrics in relation with each other? Researchers will compare two groups of participants-those without dry eye symptoms and those with dry eye symptoms-to see if blinking measures differ between them and whether these measures relate differently to tear film quality. Participants will: * Answer a questionnaire about dry eye symptoms * Have their visual correction measured (if they wear glasses) * Undergo non-invasive assessments of tear film quality using an imaging device * Complete three types of blink tasks, each repeated three times, including measurements of blinking and of tear film stability

This study will involve the collection of follow-up data for patients who previously participated in the Sjogren's International Clinical Collaborative Alliance (SICCA) study at the University of Pennsylvania. Clinical data and specimens will be collected from subjects with objective evidence of dry eye who were or were not diagnosed with Sjogren's syndrome at the time of their initial participation in the SICCA study. Specimens will be collected from participants which will include tears, saliva, whole blood, serum, DNA and possible labial minor salivary gland biopsies when indicated. All individuals will participate in a standard evaluation protocol including an oral, ocular and physical examination, objective tests for dry eyes and dry mouth and, whenever necessary, a labial minor salivary gland biopsy. The biopsy requirement is waived for those who have already had positive lip biopsies in the past.

Dry eye disease (DED) is a common eye condition that is becoming more widespread. Detecting it early, keeping track of its progression, and following up regularly can help protect vision and prevent serious complications. However, due to a shortage of ophthalmologists, limited access to eye care services, and disparities in care quality, many patients receive infrequent or insufficient clinical consultations. To address these needs, a portable automatic ocular surface imaging device (PAOSID) that attaches to a mobile phone has been developed. This device uses three types of light including white, infrared, and cobalt blue light to capture clear images and videos of the eye's surface. It also has a smart system that automatically takes high-quality images, allowing patients to use it at home independently. This device may help detect early signs of DED and monitor eye health more easily.

The purpose of this research study is to understand the mechanism of action of low level light therapy and also potentially yield markers associated with good treatment response. Low-level light therapy is light-based treatment delivered through advance eye-light device. This therapy uses light energy to provide energy to the meibomian gland cells to slow down age-ing, improve tear stability and reduce inflammation.
